GEARING FOR WASHING-MACHINES.

srnoIrroA'rIoN formingm of Letters Patent Ref/07,949, dated August 26, 1902.

, Application 1118a March 22, 19oz.

To all whom, it mag concern.-

Be it known that I, JAsPnRH. STANFI a citizen of the United States, residing at of which the following is a specification. This invention relates generallyto washing-machines, and more particularly to that class known as agitator washing-machines, in which the agitating-rubber is intermittently rotated in opposite directions.

The object of the invention is to provide an improved driving mechanism whereby the agitator is rapidly revolved by means of a steady and easy movement of the crankwheel; and another object of the invention is to provide a driving mechanism which can be attached to the hinged-lid, so that the entire driving mechanism can be tn rned back whenever the lid is opened, and thereby avoid the necessity of removing one or more parts of the driving mechanism for the purpose of opening the'lid.

With these objects invview the invention consists in'the novel features of construction and arrangement of the various parts, all of which will be fully described hereinafter and pointed out in the claims.

In the drawings forming part of this specification, Figure 1 is a perspective View of a washing-machine provided with my improved construction of driving mechanism. Fig. 2 is a top plan view of the same. Fig. 3 is a side elevation partly in section, to illustrate the agitator within the tub. Fig. 4: is a detail sectional view illustrating the connection between the drive-shaft and reciprocating rack-bar.

Referring to the drawings, A represents a tub, which is preferably constructed of galvanized iron and corrugated and provided with suitable rack-sockets A, into which are fitted supporting-legs A A suitable top A is arranged in the tub, said top being provided with a hinged cover A, to which the entire driving mechanism for operating the agitator B is attached. This agitator B comprises a shaft B, which projects upwardly through the hinged cover and carries a pinion C. The lower end of the shaft has a disk B connected therewith, from the lower face Serial No. 99,479. (No model.)

of which project the rubbing or scrubbing pins B The pinion C intermeshes with a raclcsegment D, which segment is connected integrally with the casting E, having the hub portion E, through which a pivot-pin E passes, said pivot-pin being connected to a plateiF, fastened to the hinged cover and through which the shaft B passes, as mostclearly shown. The casting is also provided with rack-teeth E upon the opposite side of the pivotpin, which rack-teeth intermesh with a rack-bar G, which reciprocates upon a rib F, formed integral with the plate F, and the said plate is also formed with an upwardly-projecting lug F through which the reduced circular end of the rack bar passes, and between the rack-teeth and said reduced portion is a frame H, in which operates a roller I, mounted upon the end of the shaft K, said shaft being journaled in the brackets F and F", integralwith the plate F, said plate projecting to the edge of the top of the tub, as most clearly shown; but'the said plate is only connected to the hinged cover so that when the said cover is open all of the driving mechanism herein described will be carried back with the cover, and thereby avoid the necessity of'removing any of the operative parts for-the purpose of opening the cover;

In practice I prefer; to construct the reciprocating rack-barwith a depending rib H which'works in a groove F produced in the rib F, thereby serving to guide the rack-bar, and consequently holding the same in its properposition duringits various movements. An antifriction-roller L is also mounted upon the plate F just to one side of the rack-bar, thereby aiding in holding the rack-teeth of the said bar in engagement with the rack-teeth of the casting E. I also prefer to provide the shaft I with a crank 1, upon which is mounted the roller 1.

It will thus be seen that I provide an exceedingly cheap and simple construction of driving mechanism for washing-machines by means of which a quick motion can be obtained by an easy revolution of the crankhandle M, and it will also be noted that the entire driving mechanism is mounted upon the hinged cover, so that the said cover can be opened at any time desired without removing or disconnecting any of the driving mechanism.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a machine of the kind described, the combination with a base-plate, of a casting pivoted thereon, said casting having internal and external gear-teeth, a reciprocating rackbar adapted to engage the external teeth, a pinion arranged for engagement with the in ternal teeth, and means for operating the reciprocating rack-bansubstantially as described.

2. The combination with a base-plate provided with a rib and guide-lug, of a casting pivoted thereon, said casting having interior and exterior gear-teeth, a pinion arranged for engagement-with the interior gear-teeth, a reciprocating bar adapted toslide upon the rib formed upon the base-plate, and through the guide-lug connected to the said base-plate, said rack-bar and exterior gear-teeth intermeshing with each other,a drive-shaft mounted upon the base-plate, and having a crankarm attached to its inner end, a roller pivotally connected to said crank-arm, a frame integral with the rack-bar and in which the roller operates, all arranged and adapted to operate substantially as described.
